NITED STATES PATENT rrrca WILLIAM s. HUNTINGTON, OF NEW YORK, N. Y.

RAILROAD-SPIKE.

SPECIFICATION forming part of Letters Patent No. 328,889, dated October 20,, 1885.

Application filed May 6, 1885.

To all whom it may concern:

Be it known that I, WILLIAM S. HUNTING- TON, of the city, county, and State of New York, have invented a new and Improved Railway-Track Bolt, of which the following is a full, clear, and exact description.

The object of my invention is to provide a safe, effective, durable, and economical fastening for railway-rails, which prevents spreading of the rails, permits of lifting the rails without removing the fastening-bolt from the tie, and which bolt does not split or tear the tie as the driven bolts or spikes do.

The invention consists of a screw-bolt having part of its head out off tangentially to the stem, said tangential surface of the head being inclined or beveled upward away from that side of the stem or shank of the bolt, to permit of the ready removal of the rail, as well as the ready replacement of the rail, substantially as hereinafter more fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved railway-track bolt. Fig. 2 is a plan view of the same. Fig. 3 is a cross-sectional view of the rail and a side view of the bolt.

The screw A has apointed end, and a head, 13, preferably made polygonal, and the under side of the head is beveled-that is, it rises from the upper end of the stem of the screw to the edge of the head-as is shown in Figs. 1 and 3. Part of the head is cut off in a plane tangential to the upper part of the stem of the bolt, the said tangential surface being inclined upward and away from that side of the stem or shank of the bolt, as at G, whereby it is obvious that when the bolt is turned so as to Serial No. 164,569. (No model.)

present the tangential surface of the bolt-heads toward the rail, the inclination of the said tangential surface will permit the ready removal of the rail, or, in other words, prevent the wedging of the latter upon attempting to remove the rail, as would be experienced were the tangential surface of the bolthead perfectly perpendicular.

In using my improved bolt a hole is first bored in the tie D, adjacent to the base of the rail E, and the bolt or screw A is screwedinto the said hole by means of some suitable keywrench or other implement, and is screwed down tight until the beveled underside of the head fits snugly on the base of the rail, and one corner or one side of the bolt-head overlaps the edge of the rail-base, and thus holds it firmly on the sleeper.

To remove the rail without removing the track-bolt, the latter is turned until its side O is parallel with the side of the base of the rail, when the rail can be lifted without striking the head of the bolt.

As the bolt is screwed into the tie, the said tie is not split nor broken, the bolt is held firmly and securely, and cannot work loose, and as no blows are delivered on the bolt, the head is not apt to break off.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent- The railway track bolt, with its screwthreaded shank or stem provided with a head having its tangential cut-off portion inclined or beveled outwardly and away from that side of the bolt, substantially as and for the purpose set forth.

\VM. S. HUNTINGTON.
